Question

lesson 3 practice problems

1. here are 3 polygons.

draw a scaled copy of polygon a using a scale factor of 2.
draw a scaled copy of polygon b using a scale factor of $\frac{1}{2}$.
draw a scaled copy of polygon c using a scale factor of $\frac{3}{2}$.

Explanation:

Step1: Understand scale factor concept

The scale factor determines the size change. If $k$ is the scale factor, new side - length = original side - length $\times k$.

Step2: Measure original side - lengths

Use a ruler to measure the lengths of the sides of each polygon.

Step3: Calculate new side - lengths

Multiply (or divide as per the scale factor) the measured side - lengths by the given scale factor.

Step4: Draw scaled polygons

Use a ruler and protractor to draw the new polygons with the calculated side - lengths and the same angles as the original polygons.

Answer:

This is a drawing - based task. For drawing a scaled - copy of Polygon A with a scale factor of 2: Measure the lengths of each side of Polygon A. Multiply each side - length by 2. Then, using a ruler and protractor (to ensure the angles are the same), draw a new triangle with the new side - lengths.
For drawing a scaled - copy of Polygon B with a scale factor of $\frac{1}{2}$: Measure the lengths of each side of Polygon B. Divide each side - length by 2. Then, draw a new polygon with the new side - lengths and the same angles.
For drawing a scaled - copy of Polygon C with a scale factor of $\frac{3}{2}$: Measure the lengths of each side of Polygon C. Multiply each side - length by $\frac{3}{2}$. Then, draw a new parallelogram with the new side - lengths and the same angles.
